This seems to be spread across multiple various posts so thought I would try to compile the options and thoughts. I had a comment about the Cabrera option and couldn't figure out where to post it, so I thought an updated universal diary might be helpful (go ahead and delete it Randy or Allen if it's not at all helpful):

A-Rod

No longer an option, re-signing with Yankees

Lowell

Reportedly has been offered 4 years from 4 different teams for 55-60 million dollars. Read this diary for more details and discussion

Cabrera

Reportedly the Sox, Angels, and Dodgers have all dangled some players as potential trade pieces. Angels and Dodgers seem to be trumping the Sox in what they are willing to offer with the Angels suggesting Brandon Wood, Maicer Izturis and Howie Kendrick and pitcher Nick Adenhart are available while the Dodgers are offering Matt Kemp, Chad Billingsley, James Loney and Andy LaRoche.
My take: If this rumor is true, forget the Angels, what are the Dodgers thinking?? Loney and LaRoche look like they will be all-stars, Kemp looks like he will be a solid hitter, and Billingsley I've always liked and looks like he will be a very solid SP. Those are 4 young, cost-controlled players who all are Major league ready (or already playing in the Majors). The Dodgers would be trading away the future of the Dodgers for one player who as many have said, might eat himself out of the Majors in the next couple of years. I don't want the Sox to even consider trying to match this offer

Rolen

Thoughts? Is he worth it? What will it take to trade for him? Do we want him trough 2010? There's thought out there that because the Cardinals don't want to be eating any part of his remaining salary and because he is begining to age an wouldbe locked up through 2010, that they will have to accept that they'll have to give him up for little  in return. If we can get him without parting with any A level prospects, maybe some combination of B-level prospects and Coco, I'm all for it.

Jed Lowrie/Brandon Moss

Take the Pedroia approach and hand over the job to a Youngster and let them run with it (moving Youk to 3B if it's Moss).
My take: I like the Moss option. He may not be as good as Lowell would be, but I think he could successfully hold down the position until either a better option is available in a year or two or until Lars matures enough to take over 1B. It's not the end of the world if we become a little weaker in one position, especially with us already getting stronger in CF upgrading from Coco to Ellsbury, and the possibility of Lugo and Drew bouncing back
